Question

Find the equation of this line:​

Answer 1

Answer:

y = 6x + 3

Step-by-step explanation:

Find the slope using the formula rise/run or Change in y/Change in x. We can find the slope by plotting 2 points on the graph. We observe that the points (0,3) and (3,0) are on the graph. Let's use this to find our slope.

First, move 3 spaces down from (0,3). Then, move 3 spaces to the right from (0,0). Count the amount you moved: 6. Therefore, the slope is 6

Next, find the y intercept. To find it, we plug in two points for x and y to solve. However, in this case, the y-intercept is already given. This point is (0,3), on the vertical line. Therfore, the y-intercept is 3.

Your equation, in slope-intercept form, now looks like this: y = 6x + 3 (y = mx + b)
